Dyno Numbers

[CincyJohn]

So when are we going to start getting tunes for Gen 2? Will there be an OFT option, and, if so, will Gen 1 OFT work with Gen 2? Can't wait to see the results of Gen 2, catless headers, and e85 dynos as I expect this to eventually be my setup.

Great numbers. What dyno is that?

Another dyno I stumbled upon. Don't know Japanese.

Numbers translate to about 200whp/169ft-lb

Couldn't find the GR86 dyno thread. Results from Revolution Garage. Please note the correction factor on the dyno of 1.15. The vehicle has all the Revolution Garage I/E bolts-ons. Just waiting for ECUtek like everyone else.

It ran a 59.602 at Tsukuba BTW.

"Tomorrow, the athletic meet is TC2000, so I had some time to spare, so I tried to measure my physical strength. The dotted line at the bottom of the graph is the data of a full normal vehicle in the latter half of ZN6, which is nearly 100 horsepower large.

TI composite chamber muffler, ECU (bolt-ons and a tune) is about 220ps (crank) horsepower, but FA20 is 220 horsepower which is 40 horsepower up because the start is about 180ps horsepower,

FA24 is 275ps horsepower plus 40 horsepower because the start of the catalog data is 235 horsepower The horsepower is expected, but the FA20 has already been original (tuned) ECU, and the GR86 FA24 has a normal computer, so considering this, it feels like the electric water pump has increased about 12 horsepower (He swapped on an electric water pump) If ECU (tuning) becomes possible, probably 290 horsepower will reach, FA24 is scary. .. .."

Here is a compiled list of all the dyno runs I could find on here, couple FB groups and GR86. Currently have 19 dyno runs averaging 214.19whp and 174.31 ft-lbs.

Edit: I only included 1st gen numbers when they were provided on the same dyno.

I'm not trying to bring anyone down. But do some reading on how dynos work. They have variation brand to brand, type to type and individual to individual. When and how it is calibrated. Also which offsets are entered and the correction factors. Weather conditions are HUGE and often overlooked. That compiled list of pulls and the average is a great idea.

I have run a SuperFlow engine dyno and a motorcycle chassis dyno at work for about 10 years. I can make the dyno gauges read anything I want. Again a grain of salt is needed with any dyno numbers.

That's exactly why I started to compile a list and look at averages. It will help mitigate outliers, both high and low, and give a better overall picture. I also included comparisons to Gen1 cars on the same dyno when available. This helps give a relative percentage increase over Gen1, along with measured HP and TQ gains. So far I have 19 cars on my list. I think at this point that average is getting pretty accurate. Where you can't just say "well that dyno is high" or "All dyno's are different".

I think it's also starting to point to some pretty obvious things. Like the FA20 was just over 100hp/liter, why wouldn't the decade newer FA24 be the same? Assuming ~15% drivetrain loss and an average of 214whp, that's 252hp, right inline with the just over 100hp/liter. Additionally the FA24 is a 20% increase in displacement which falls inline with the current averages, showing an increase of 24.25% HP and 26.06% TQ over Gen1, pointing to potentially slightly more aggressive or refined tuning.

All common knowledge here fortuity.

Considering that a dynojet calibrated for crank horsepower shows 220 or so hp I'd say that the factory didn't underrate the figures but maybe overrated the fa20?

I've read that, but it just doesn't make sense. On dyno jet Gen1s make like 170-175hp, if that's 'crank' then that's just way off. We can also look at things like 0-60 and 1/4 mile times (~5.4s and 13.9s@101mph) and a 214hp 2800lb couldn't do it that fast.

But also, it's literally impossible for a chassis dyno to measure 'crank' hp. There is no way it could possibly know drivetrain losses. The only way would be to take the engine from the car, dyno it on an engine stand and them put it back in the car and measure the difference.

And other dynos, like mustang are reading pretty much right on par with them as well.

Lastly, comparing it to other cars with similar power and weight also go to show the numbers are about right

This. Compared to say a 350z that runs very similar times/traps puts it around ~245-248Bhp. Subaru must have listened to Toyota more this time.

One could easily think so. On the race track i have super similar speed trace on the straight as my other car, a porsche 924 turbo. Which back then had 165hp at the hubs, and not as good Cd as the 86.
